Patent FR-2467448-A1 (FR)
IPC: G01R31/36
Filed: 1979-10-12
Abstract: This anti-fraud system includes a process and devices for avoiding fraud on the price indicated by an electronic taximeter. The taximeter apparatus, which includes a luminous display unit and a computing unit, is supplied with d.c. voltage V by the vehicle battery. One particular fraud, made more difficult by this system, involves voluntary cut-off of the voltage supply to the meter. To execute this fraudulent maneuver the cabdriver firstly starts the meter, and records a price on the fare meter, with no passenger in the taxi. Secondly, before a customer is picked up, the operator cuts off the current supply to the meter, which extinguishes the fare display. Thus, as the customer enters the cab, it is not apparent that the meter has already been run-up to a non-zero value. To preclude this maneuver, the anti-fraud system has a first comparator which compares the voltage V with a reference voltage Vr and emits a constant voltage Vc if V<Vr and a zero voltage if V>Vr. Another comparison device compares the duration during which V remains lower than Vr with a reference time period duration. The computing unit and the display unit are returned to zero each time the reference time period duration is exceeded.

Title: Antitheft mechanism for vehicles - is integral with ignition switch and is moved by spring to lock steering(BR 22.481)
Inventor: REMONTET YVES
IPC: B60R25/02
Filed: 1979-10-19
Abstract: The vehicle anti-theft mechanism associated with the ignition lock has a bolt which moves parallel to its axis between locked and unlocked positions. The mechanism allows a large number of parts to be common to all locks as opposed to the wide variety of part types required by conventional transverse shaft type locks. The bolt shaft (6) is mounted within the ignition lock housing and moves axially driven by a spring (7) as the ignition key (3) is turned. The shaft is cranked and terminated in a radial finger (9) which engages with an oblique slot, angled at forty five degrees, in the bolt proper (13). The angle is chosen to ensure orthogonal and non-orthogonal movement of the bolt as the ignition key is rotated. The bolt movement is into or out-of a slot on the steering column providing a lock on its movement.

Title: Cultivation tool shaft bearing - has radial supporting sleeve clamped between parts of split holder
IPC: A01B71/04
Filed: 1980-03-20
Abstract: The shaft bearing system is used on an agricultural ground cultivation tool. The tool elements are supported in a frame at intervals along a shaft, there being sleeves on the shaft accommodating ball- or roller-bearings, and holders enclosing the bearings and fixed to the frame. A separate sleeve (10) encloses the bearing (4) and supports it in the radial direction, while the holder (2, 3) is split, its two parts being clamped round the sleeve. To form an enclosed bearing housing the two shaft sleeves (5, 6) are stepped, forming an annular grooe for the bearing between their flanges (8, 9), which fit inside the holder.

Title: Lock for front door - has second lock barrel which when released using combination, allows access for emergencies
Inventor: NERO CLAUDE DEL
IPC: E05B35/08
Filed: 1980-07-28
Abstract: The front door lock for a house contains a lock barrel which, when turned by a key, causes movement of at least one latch (15). The latch can also be moved by turning a second lock barrel (37) using a different key when the barrel has been released by an external combination lock (65) or by a solenoid operated from inside the house. Movement of the second barrel (37) is transmitted by three meshing pinions (28,26,25) to the latch release. The lock allows emergency access to old peoples homes by a warder holding the second key and knowing the combination.

Patent FR-2491298-A1 (FR)
IPC: A23G1/02
Filed: 1980-10-08
Abstract: The invention relates to a process for pasteurising and roasting a cocoa pulp mass and a device for implementing this process. The process is characterised in that, successively, the cocoa pulp mass is distributed in the form of a thin layer on a first support which is exposed to heat radiation, removed from this first support, kept in the open for a predetermined time, again spread in the form of a thin layer on a second, constantly cooled support and removed from the second support. The associated device comprises a first rotary drum (1), on the wall (9) of which the pulp mass to be treated is distributed in a very thin layer in order to be heated, a storage container (27) filled with the heated pulp mass, the useable volume of which can be adjustable by displacing a piston (32), and a second drum (20) for cooling the pulp mass which has a dwell time in the container (28). Application in the chocolate industry.

Title: Proximity sensor for automatic control of mining machine - uses ultrasonic transmitter to provide threshold level signal for safety control via UHF control transmitter
Inventor: MARTEL JOEL
IPC: G08G9/02
Filed: 1980-10-31
Abstract: A portable controller (3) transmits UHF signals via an antenna (4) to a receiving antenna (6) on a machine (1). The receiver (5) is connected via a decoder (7) to a driver stage (8) for relay circuits (9). A direct connection (12) from the receiver to the driver circuits stops the control unit (11) when the UHF transmission ceases. An ultrasonic transmitter (13) sends signals from a double loop antenna (14) to a low frequency receiver (15) with a frame antenna (16) in the portable controller. The transmitter comprises an LF oscillator driving a power amplifier via a buffer stage. A transformer enables the signal to be connected to one antenna loop while the other loop is connected via a phase shift circuit to produce an omnidirectional transmission. The receiver contains threshold comparators to prevent operation of the UHF transmitter if the operator approaches the machine to closely.

Title: Power cable conductors suspended internally by resin impregnated ties - to use gaseous insulation for long distance high voltage distribution
Inventor: THURIES EDMOND
IPC: H01B9/06
Filed: 1981-07-01
Abstract: Multiple conductors within long distance high voltage power transmission cables are suspended within a hollow sheath by pairs of sets of three ties supported on rigid struts between annular collars so that the ties and the lengths of conductor between them are suspended in tension. For groups of conductors, one tie in each set is longer than the others so that each conductor is carried at a position shifted radially from the centre of the cable and offset angularly relative to the other conductors, e.g. to maintain sufficient spacing between conductors carrying three complementary phases. Pref. the ties are made of extruded glass fibres impregnated with polyester or epoxy resin, in a sheath filled with an insulating gas such as compressed air, SF6, hydrogen or a freon. Opt. the sheath has a conductive body or external surface to dissipate any induced charges e.g. may be of steel or aluminium alloy. Opt. the sheath is surrounded by a coaxial casing separated by a clearance swept by a circulating insulating gas. Individual conductors may pass through an annular collar used as a sensor for the current. Lighter than cables incorporating liquid or solid insulation, coupled with a relatively low electrical capacity. Opt. one of the conductors may be earthed via a lateral branch passing through an insulating seal to an earth connection via a coil.
